To Vthe. said cross-pieces are fixed the vertical beaters D D, which have cylindrical holes through them from end to end, for conveying the air down to thebottom of the churn. The crosspiece C is recessed on its lower end and rear edges, as shown at a,-wh ereby, in its rotary movement in the cream,'

partial vacuums are formed behind and under each arm of the cross-piece where the said cylindrical openings through the beaters communicate with the s-rid cross-piece, which greatly facilitates the admission of air to be mixed with the cream, from which very beneficial resultsare obtained in the Vprocess of-churning. as is well understood.
